Specication of Letters Patent.

Patented Nov. 5, 1912.

Application filed April 15, 1912. Serial No, 690,857.

To all whom it 'may concern:

Be it known that I, lViLLiAM C. Horrns, a citizen of the United States,and a resident of Dawson, in the county of Richard son, State ofNebraska, have invented a new and useful Improvement in Eveners, ofwhich the following is a specification.

ln the drawings :i Figure 1 is a plan view of the improvement; and Figs.2 and 3 are sections on the lines 2 2 and 3 3, respectively, of Fig. 1.

In the presentl embodiment of the invention the bar 1 corresponding tothe usual double tree, is provided with a clip 2 at its center and onits rear face for connection with the tongue or draft bar 3. A ring 4 isprovided for making the connection, the said ring engaging the clip 2,and the eye' 5 secured to the end of the tongue by means of bolts 6,which pass through the tongue and of the tongue and connected to the eyeat their front ends.

One end of the bar 1 is provided with a plurality of openings 8 arrangedin a spaced longitudinal series, and a substantially U- shaped clip 9 isconnected to the said end of the bar by means of a bolt 10 which passesthrough bearings 11 in the ends of the arms of the clip and through oneof the openings 8.

A swingle tree 12 is connected to the clip by means of a ring 13, thering engaging the clip at one side and an eye bolt 14 at the oppositeside. The eye bolt 14 is passed through the swingle tree and is held inplace by a nut 15. The opposite end of the bar 1 is provided with asingle opening, in which is received one of the arms 16 of a doublecrank 16--17. Each of the arms 16-17, which are offset laterally fromeach other, is threaded, and the arm 17 is passed through an opening ina second bar 18. The bar 18 is arranged directly above the bar 1, and isof such length that, when one end of the bar 18 is in register with oneend ofbar 1, the opposite end of bar 18 will extend beyond the tongue.Each of the crank arms 16-17 is engaged by nuts 19, the said nuts beingarranged on opposite sides of the adjacent bar, and each of the bars 1and 18 is provided with a hook 20 and 21, respectively, at the endadjacent to the crank. A plate 22 connects the hooks, 4and the saidplate is provided with a longitudinal series of openings 23, the endopenings of the series being engaged by the hooks (Figs. 2 and `eachother as'respects their length.

An S-shaped clip or double hook 24 has :one ofits ends or hooksengagedwith one of vthe intermediate openings of series 23, and

the other end or hook with the clip 25 of a clip 29.

rEhe double hook 24 and the doubletree `may be raised or lowered withrespect to bar 1 1, by engaging the hook with dierent opeiiings ofseries 23, and the opposite end of the bar 18 is provided with alongitudinal se` ries of openings 30. A substantially U- shaped clip 31has its arms extending on opposite sides of the bar atl the said end,and a 4pin 32 is passed through bearings 33 at the ends of the arms andthrough one of the openings of series 30.

through arms 7, arranged on opposite sides A swingle tree 34 isconnected to the clip 31, by means of a ring 35, which engages the clipand an eye bolt`36, connected to the swingle tree at its center. The bar18 is also pro- ;vided with a longitudinal seri-es of openings 37 nearthe opposite end from openings 30,

and an inclined draft bar has one end con- A pin 42 is provided forconnecting the ,brace to the bar 18, the said pin passing through theeye 41 and one of the openings `of series 37.` A cotter pin 43 is passedtransversely of crank arni17 above the nut. A reinforcing shoe 44 isarranged on opposite ,faces ofthe bar 1 at the clip 2, and similar shoes45 are arranged on the said bar and on `bar 18 at the clips 9 and 31,respectively.

The swingle trees 12, 28 and 34 are provided with the usual trace hooks46 for the attachment of the traces. It will be noticed that the bars`1and 18 bear a certain relation to Bar 1 in actual use will be about 6feet in length, that is, three feet on each side of the tongue, which isa draft bar rather than a tongue.

The plate 22 is six inches in length, and bar 18 is four feet in length.The two draft animals at swingle trees 12 and 34 are bal-r` anced by thetwo draft animals at swingle trees 28. The said animals at trees 28pullagainst the ends of bars 1 and 18. The relael since the crank 17 isone foot from the near end of bar 18. j

The draft animals pull against the one at swingle tree 12, and the threeare balanced against the one at tree 12, and also against each other. Avery great range of adjustment is permitted by the openings 8 forswingle tree 12, the openings 30 for swingle tree 34, the openings 23for double tree 26, and the openings 37 for the draft rod 38.

The principal advantage possessed by the improved evener, is that whenattached to a plow, the draft animal working at the end ofthe bar 1 maywalk in the furrow, and the trace chains will be on a level. That is,the draft animal attached to the swingle tree 9 may walk in the furrowat a lower level than the other draft animals and yet have a straightpull. With the ordinary evener, the trace chains of the animal in thefurrow would incline upwardly toward the evener. The trace chains of thedraft animal in the furrow may be attached siX inches lower than thoseof the draft animal pulling on the bar 18, provided that the hook 24 isat the upper end of the bar 22. For different depths of furrow thedouble tree 26 may be adjusted on the bar 22 in accordance with thedepth and when the adjustment is so made, each anini al connected withthe evener pulls with horizontal trace chains.

The animal attached to the inner end of the bar 18 is always balancedwith respect to' the team on the hook 24, regardless of whether' thesaid animal on swingle tree 34 is ahead or behind the team on doubletree 26. This balance is due to the crank arms 16-17. It is obvious thatwhen the animal on swingle tree 34 is ahead of the team on double tree26 the relative distance between the connection of the crank arms 16-17is varied and this variation occurs automatically. In addition theimproved evener can be attached by means of a tongue or by means of achain without a tongue. Side draft is also lessened by the balance andadjustment of the parts.
